CARI-Rooi?.

Specification of vLetters Patent. Patented Aug'. 29, 1916.

Application led November 7, 1912. Serial No. 730,003.

To all whom t may concern.'

Be it known that I, RICHARD WEBB BUR- NETT, a resident of the city ofMontreal, in the Province of Quebec and Dominion of Canada, haveinvented certain new and useful Improvements in Car-Roofs; and I d0hereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates particularly to the type of roofs having carlinesofinverted U-form and consists, broadly speaking, of a carlineconstructed of T-crosssection with downwardly turned flanges and havinghangers depending from the web or leg of the T for supporting bearingplates locked in place with sufficlent clearance between their uppersurfaces and the flanges of the carline to confine the upturned sideedges of the roof sheets without abrasion.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings formingy a part of' this specification inwhich similar reference characters indicate the same parts, and wherein:

Figure 1 is a transverse sectional view of portions of a roof and upperportion of the .side of a car containingthis invention; Fig.2 is atransverse vertical sectional view of my improved carline taken on lineA A Fig. 1; Fig. 3 is a horizontal sectional view taken on line B B Fig.2, Fig. 4 is a detail perspective view of the means for suspending theroof-sheets from the carline, and Fig. 5 is a horizontal sectional viewtaken on line X X Fig. 1.

rllhe main supporting members of my improved roof consist of a series ofcarlines 3 of T- cross-section and having their side anges 4 turned downto protect the upturned side edges of the roof sheets. A series ofhangers 5 are riveted at their upper ends to the webs or legs 25 of thecarlines while their lower ends carry plates 6. These plates extendslightly beyond'the width of the carlines and in length are sufficientlygreater than the width of the hangers to impart the required rigidity tothem to support the roof-sheets. In order to support these plates, thehangers are slotted at 15 the slots extending upwardly to approxiqmately thelower edge of the web or leg of the T and wedge-shaped pinsdriven into these slots rigidly clamp these plates there between the webor leg of the carline.

The roof-sheets are supported, as before mentioned, upon the bearingplates and have their upturned side edges overhung by the turned downflanges of the T, sufficient space between the turned down anges and thebearing plates affording the necessary clearance to accommodate theroof-sheets without abrasion thus permitting them to move freely duringthe working of the car.

In assembling the parts of my invention the hangers are riveted to thewebsor legs of the T before the flanges are turned down then theroof-sheets are held in place having their upturned side edges withinthe turned down flanges of the carline the bearing plates are slipped onand the pins driven and their ends turned down to hold them in place.

The earlines are connected at their ends to the side plates of the carby having the ends of their flanges 4 turned laterally as at 10, Fig. 5and perforated to receive bolts 12, the sheets being slotted toaccommodate distance pieces 14 through which the bolts project.

What I claim is as follows 1. The combination with a carline of T-cross-section having turned-down flanges, of a series of hangersfastened to and depending from the leg of the T, a series of bearingplates detachably engaging the hangers, means whereby one of the bearingplates is supported by each hanger, and roof sheets having turned-upside edges supported by a plurality of said bearing plates with theupturned side edges within the turned-down flanges of theV carline, saidsheets being spaced from said carline.

2. lIhe combination with a carline of T- crosssection having down-turnedflanges, of a hanger fastened to and 'depending from the leg of the T, abearing plate detachably engaging the hanger and having its upwardmovement limited by the lower edge Vof the leg of the T, taper pinsinserted beneath the bearing plates and engaging apertures therein forholding the bearing plates from downward movement, and roofing sheetsname to this specification in the presence of having upturned side edgessupported on two Witnesses. said bearing plates with the upturned sideMontreal, November 2nd, 1912.
